Most any auto parts store will have a 'set' of "fuel line quick disconnect" tools, in the common 5 or 6 sizes. They are cheap to buy, and you would need two sizes of them to disconnect the fuel lines that connect to the fuel rail on a 2nd generation Escort like yours.
As far as I know the connections at the fuel filter, and at the fuel tank dont require this kind of tool. Instead for these connections you either pull the plastic goody at the connector sideways - outward or push it in further (I cant recall, but they look like they were made to be pushed 'inward'.), while pulling on the fuel line, and it should come apart. It wont be 'willing', due to having sat on there for months or years, so it will take quite a pull. If you dont have the plastic 'locking piece' either pushed all the way in, or pulled part of the way out - you will end up breaking the fitting; which I think is called a 'retainer'. That is for the ones on the fuel filter and the fuel tank (which you get to by lifting the rear seat and taking off an access cover). I always use pliers to push these locking tabs around.
For the fuel rail, you slide the correct sized fuel line quick disconnect tool down over the fitting on the rail, so it pushes the circular spring "outward". You then have to pull the fuel fitting downward from the hose end. You cant get it off by pushing down from the fuel rail end. The tool is ONLY for making the circular spring move outward. This releases the fitting on the lower end that the fuel line is connected to. It will take quite a bit of a pull to get the fitting to seperate from the fuel rail. Not the easier place to get a good grip either. It always takes me many minutes to get these apart, even though I have done it a few times.

There are a couple of small lines connecting to the top of the tank. One is a vent for letting the air bubble escape when you are filling the tank, another goes to the vapor recovery canister. If they have rotted, they would leak a little due to the splashing of fuel as you drive the car. You should be able to see these hoses if you drop the tank about an inch or two, and look in with a mirror -sideways- at the top of the tank.

Why does Ford use these connectors anyway? I'm doing an Escort motor swap and yes, I had to borrow that special tool from a buddy. Did a Nissan Sentra engine swap last month and those lines to the fuel rail were just regular rubber hoses with clamps.

Not to hijack the thread, but since we're kind of on the subject, what's the easiest way to drain the Escort wagon's gas tank? The gas in this Escort has been in there a long time (2+ years) and has gone bad. Need to drain and flush the tank with fresh gas before trying to start up the new motor.

Thanks,
James

I havent needed to drain mine, but; I would probably use a long clear tube to siphon it out - having unclipped the rear seat bottom, removed the access lid, and unscrewed the locking ring. That would be my first choice.
Its fairly hard to get the fuel filller neck disconnected from the large diameter rubber hose that enters the tank. The rubber tube doesnt seem very pliable, and it may leak when you put it back on: but that would be another way to introduce a siphon hose into the tank.
For siphoning I prefer to buy the clear vinyl or polyethelene hose sold in hardware stores. That way I can see the fuel coming when Im drawing it up (by sucking on it).
My 92 Escort wagon sat for about 2 years before I got around to rebuilding its engine/transmission. It had perhaps 1/4 tank or less of fuel in it. So... I just added enough fresh fuel from Jerry cans to bring it up near full, and never had any ill effects from doing it that way (diluting the old fuel with new).
The oldest fuel I ever tried to use was about 6 years old - and mixed 50% with fresh gas. That was in a car with a carburetor, and it worked okay - though the spark plugs misfired when cold until the old fuel was used up.
